BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a water cooling fan, particularly to one provided with multiple air outlets.

2. Description of the Prior Art

Generally, most of factories are in operation day and night and the machines in the factory will produce high temperature when they are in an operating state and as a result, the working environment in the factory becomes extremely hot with great discomfort; therefore, cooling fans are developed and used for modulating working temperature in the factory. A conventional cooling fan, as shown in FIG. 1, includes a housing 1 having two sides respectively bored with an air intake 2 and an air outlet 3 and its interior provided with a fan unit 4 and an evaporative cooling pad 5, which is a structure formed of plural wavy sheets or a honeycomb-shaped structure. The housing 1 is further provided in the interior with a water storage box 6 having one side installed with a pump 7 connected with a water tube 8, which has another end connected with a water discharge device 9 positioned on the evaporative cooling pad 5. Thus, when the pump 7 is stared to pump water from the water storage box 6 to have the water conveyed to the water discharge device 9 and simultaneously, the water discharge device 9 will discharge water to have the water sprinkled on the evaporative cooling pad 5 and then, the water will flow back to the water storage box 6 to form a circulation. Subsequently, the fan unit 4 is started to have outside hot air getting into the housing 1 through the air intake 2 and continuously passing through the evaporative cooling pad 5. At this time, the hot air will carry out heat exchange at the evaporative cooling pad 5 to have the air that passes through the evaporative cooling pad 5 turned into cold air and finally, the cold air is exhausted out through the air outlet 3 via the fan unit 4.

However, the above-mentioned conventional cooling fan has the following defects:

1. Since the conventional cooling fan is provided with only one air outlet, and the mechanical equipment in the factory building produces heat source incessantly; therefore, although the conventional cooling fan can lower the temperature of the factory building, yet the effect is limited in temperature modulation, much less carrying out cooling and temperature modulation to many people, machines or regions. Thus, heat dissipation effect of mechanical equipment is imperfect and hence likely to result in energy consumption and cause damage.

2. The whole volume of the conventional cooling fan is comparatively large so it needs to take a lot of exertion and time to move the housing 1 to a specified location, thus wasting labor and time and causing much inconvenience to a user. Therefore, observing foresaid drawbacks, the inventor of this invention thinks that the conventional cooling fan is necessary to be further ameliorated and hence devises this invention.

SUMMARY OF THE INVENTION

The objective of this invention is to offer a water cooling fan with multiple air outlets, able to carry out cooling and temperature modulation to multiple designated regions, machines or persons.

The water cooling fan with multiple air outlets in the present invention includes a housing having two opposite sides respectively provided with an air inlet and a first air outlet and having its topside bored with at least one second air outlet. An evaporative cooling pad is provided at the location of the air inlet of the housing, and a water pump is installed at the bottom side of the housing and connected with a water discharge tube, which has another end extending out of the topside of the evaporative cooling pad, and the housing has its bottom side filled with cooling water. At least one air exhauster is installed at the location of the first air outlet of the housing and formed with an air suction opening and an exhaust vent, with the air suction opening communicating with the interior of the housing. An air guide casing is mounted at the location of the exhaust vent to make the exhaust vent communicate with both the first air outlet and the second air outlet. At least one air discharge tube is correspondingly disposed at the location of the second air outlet of the housing, extending outward to the outer side of the housing and able to be adjusted in air discharge position in accordance with need.

In using, the water pump is started to pump the cooling water in the housing and have the cooling water discharged via the water discharge tube and sprinkled on the evaporative cooling pad and simultaneously, the air exhauster functions to have the interior of the housing forming a negative pressure state to enable outside hot air to pass through the evaporative cooling pad and form cold air to be led into the interior of the housing. Meanwhile, the air exhauster functions to have the cold air exhausted out through the exhaust vent so that the cold air can be discharged through both the first air outlet and second air outlet. By so designing, the water cooling fan of this invention can carry out cooling and temperature modulation to a designated region via the first air outlet and can also make use of the air discharge tube to carry out temperature reduction to machines or persons. Thus, compared with the conventional cooling fan that is provided with only one air outlet, the water cooling fan with multiple air outlets of this invention is much better in heat dissipation rate and in cooling effect, able to enhance efficiency of mechanical equipment and attain efficacy of energy saving.

The pivotal plates 61 are connected with the toggle 62 by means of plural connecting rods 63, letting the air discharge cover 43 able to be pivotally turned bias in all directions.

In using, referring to FIGS. 3 and 4, firstly, the water pump 15 is started to pump the cooling water filled at the bottom side of the housing 10 and have the water discharge tube 16 discharging the cooling water and sprinkling the cooling water on the evaporative cooling pad 13. Meanwhile, the cooling water passing through the evaporative cooling pad 13 will flow back to the bottom side of the housing 10 to from a circulation and hence, the water passing through the evaporative cooling pad 13 can be once more pumped to the water discharge tube 16. Subsequently, the air exhauster 30 is started to have air in the housing 10 pumped into the air-guiding casing 20 to let the interior of the housing 10 formed into a negative pressure state to enable outside hot air to pass through the evaporative cooling pad 13 to carry out heat exchange and form cold air to get into the housing 10. In the meantime, the air exhauster 30 functions to have the cold air pumped into the air-guiding casing 20 to enable the cold air to be discharged through the first air outlet 12 and the air discharge tube 40. By so designing, the water cooling fan of this invention can not only carry out cooling and temperature modulation to designated regions via the first air outlet 12, but also make use of the air discharge tube 40 to carry out temperature reduction to a single machine or person. Compared with the conventional cooling fan that is provided with only one air outlet, the water cooling fan with multiple air outlets of this invention is much better in heat dissipation speed and cooling effect, able to elevate efficiency of mechanical equipment and attain efficacy of energy saving.

Referring to FIGS. 2 and 4, since the air discharge tube 40 is provided with the support frame 44 at an inward side adjacent to the housing 10, and the air discharge tube 40 is made of plural extensible tubes 41 and plural hollow tubes 42 connected together; therefore, the air discharge tube 40 is flexible and bendable via the extensible tubes 41.
